fitting.exponentials

fitting.exponentials(x, y0, *p)

Sum over a variable number of decaying exponentials with constant offset.

Parameters:
  • x (array) – x-values.
  • y0 (float) – Offset.
  • p (variable) –

    Coefficients of exponentials. For every exponential provide

    • A amplitude (can be negative),
    • dx decay constant (can be negative, which results in a growing exponential).
Returns:

f(x) = y_0 + \sum_i A_i e^{-x / \Delta x_i}.
